Atomic physics needed to measure fields in stars It might be possible to measure the magnetic fields inside the Ni/H reactor by analyzing the light emitted by the LENR reaction. Very strong magnetic fields present in strongly magnetic stars have been measured using the character of the light that these stars emit. Zeeman lines and the characterization of circular polarization of the emitted stellar light can be converted to magnetic field strengths. >From the DGT ICCF-18 paper: “For specific parameters measurements, such as the excited levels of H2 or hydrogen atom excitation to their Rydberg states or the magnetic field emissions, a modified version of the Hyperion R5 reactor, as described in the section 2.1, was used. In such measurements, photoemissions from Rydberg state (5<n<85) species, such as H, were detected and measured using Raman type spectroscopy through a “spy-eye” attached in the reactor, while mu metals were removed.” By the way, in strong magnetic fields, measurement of Rydberg states becomes chaotic. http://www.spectro.jussieu.fr/Chaos/perso/delande/articles/23.pdf Chaos and atoms in a strong magnetic field.
